PEG-220
Safety score · 0–100
Good
Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.
A high molecular weight polyethylene glycol (~220 EO units) acting as a thickener, binder, and film-former in cosmetic products, with negligible skin penetration due to its large polymer size.
PEG-220 is a polyethylene glycol polymer with an average of 220 moles of ethylene oxide per molecule, giving it a molecular weight in the range where skin penetration is essentially negligible. It functions primarily as a viscosity-controlling agent, binder, and humectant in cosmetic formulations. EU Regulation (EC) 1223/2009 does not restrict high molecular weight PEG polymers. Purity considerations (residual ethylene oxide, 1,4-dioxane, and catalyst metals) are the primary quality concerns, and compliance with SCCS Notes of Guidance ensures safety at typical use concentrations.
Skin benefits
- Thickens and stabilizes cosmetic formulations
- Provides humectant film on skin surface
- Inert polymer with broad formulation compatibility
Known concerns
- Residual 1,4-dioxane and ethylene oxide must be controlled per SCCS standards
- May contain trace heavy metal catalysts from polymerization
